Versuchsvorschrift

A mixture of tert-butyl 2-((4R,6S)-6-(hydroxymethyl)-2,2-dimethyl-1,3-dioxan-4-yl)acetate (10 grams), methanol (80 ml), n-butyl amine (20 ml) and potassium carbonate (10.6 grams) was heated to 40-45° C. and stirred up to completion of the reaction. The reaction mixture was distilled under reduced pressure and methylene chloride (100 ml) was added to the obtained residue at 25-30° C. and stirred for 15 minutes. The unwanted solid was filtered off and the filtrate was distilled off under reduced pressure to get the title compound.
